○ 42% de 150
○ 78% de 250
○ 54% de 350
○ 3% de 20
○ 7% de 560

Answer 1

42% de 150

150 × 42 = 6300

6300 ÷ 100 = 63

42% = 63

El 42% de 150 es 63

78% de 250

250 × 78 = 19000

19000 ÷ 100 = 195

78% = 195

El 78% de 250 es 195

54% de 350

350 × 54 = 18900

18900 ÷ 100 = 189

54% = 189

El 54% de 350 es 189

3% de 20

20 × 3 = 60

60 ÷ 10 = 0.6

3% = 6

El 3% de 20 es 0.6

7% 560

560 × 7 = 3920

3920 ÷ 100 = 39.2

7% = 39.2

El 7% de 560 es 39.2

Answer 2

Respuesta:

Solo realiza regla de 3

Explicación paso a paso:

1)

150 --- 100%

x --- 42%

42 × 150 = 6,300

6,300 ÷ 100 = 63

R = 42% = 63

2)

250 --- 100%

x --- 78%

78 × 250 = 19,500

19,500 ÷ 100 = 195

R = 78% = 195

3)

350 --- 100%

x --- 54%

54 × 350 = 18,900

18,900 ÷ 100 = 189

R = 54% = 189

4)

20 --- 100%

x --- 3%

3 × 20 = 60

60 ÷ 100 = 0.6

R = 3% = 0.6
